Il permet de filtrer les particules. Son bon fonctionnement assure propret\u00e9 et puissance \u00e0 votre voiture. En cas de probl\u00e8me, il sera possible de le r\u00e9parer ou de le remplacer.<\/p>\n<p><!--more--><\/p>\n<h2>Reconnaitre que le catalyseur est bouch\u00e9<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-209\" src=\"http:\/\/www.tuningfever.fr\/wp-content\/uploads\/2020\/09\/catalyseur-boucher.jpg\" alt=\"\" width=\"280\" height=\"182\" \/>Diff\u00e9rents sympt\u00f4mes permettent de reconnaitre que le catalyseur rencontre quelques difficult\u00e9s. Parfois, le probl\u00e8me se manifeste par un manque de puissance du moteur. Pour en avoir le c\u0153ur net, d\u00e9branchez le circuit d&rsquo;\u00e9chappement avant le catalyseur ou pot catalytique. Si vous constatez que la voiture gagne en puissance, le souci vient de cette pi\u00e8ce. En bougeant le pot catalyseur, vous ne devriez rien entendre. La pr\u00e9sence de bruit lorsque vous le secouez indique une anomalie.<\/p>\n<h2>D\u00e9bouchage du pot catalytique automobile<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-210\" src=\"http:\/\/www.tuningfever.fr\/wp-content\/uploads\/2020\/09\/catalyseur-nettoyer.jpg\" alt=\"\" width=\"281\" height=\"180\" \/>Le meilleur moyen de venir \u00e0 bout d&rsquo;un catalyseur bouch\u00e9 serait le remplacement. Cela dit, vous pourrez user d&rsquo;astuce pour permettre \u00e0 la voiture de fonctionner normalement en attendant la nouvelle pi\u00e8ce. Concr\u00e8tement, il faut vous d\u00e9barrasser de l&rsquo;alv\u00e9ole \u00e0 l&rsquo;int\u00e9rieur du pot catalytique. Mais, laissez en place le pot. Cette technique permet de redonner de la puissance \u00e0 la voiture. Il y aura davantage de bruit. Puis, ce ne sera pas un geste tr\u00e8s respectueux envers l&rsquo;environnement.<\/p>\n<h2>Un remplacement de la pi\u00e8ce s&rsquo;impose<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-211\" src=\"http:\/\/www.tuningfever.fr\/wp-content\/uploads\/2020\/09\/catalyseur-remplacer.jpg\" alt=\"\" width=\"280\" height=\"180\" \/>Un moteur dysfonctionnant peut \u00eatre \u00e0 l&rsquo;origine d&rsquo;une d\u00e9gradation d&rsquo;un catalyseur. Avant de remplacer ce dernier, il est pr\u00e9f\u00e9rable de trouver la vraie origine du probl\u00e8me. Quoi qu&rsquo;il en soit, la m\u00e9thode pour atteindre cette pi\u00e8ce du syst\u00e8me d&rsquo;\u00e9chappement reste la m\u00eame. Soulevez la voiture suffisamment haut pour voir le dessous. Aspergez de d\u00e9grippant les vis qui se trouvent autour du pot catalyseur. D\u00e9montez cette pi\u00e8ce. Refaites l&rsquo;op\u00e9ration en sens inverse, mais en prenant un nouveau catalyseur. Le mieux serait de changer les joints d&rsquo;\u00e9tanch\u00e9it\u00e9. D\u00e9marrez la voiture et \u00e9coutez le bruit du moteur avant de le poser sur terre et de partir.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Le catalyseur est une pi\u00e8ce du syst\u00e8me d&rsquo;\u00e9chappement.
